  • Forwarding classes and loss priority enhancement (QFX10002, QFX10008, and QFX10016)—Starting in Junos OS Release 22.1R1, we’ve increased the number of supported forwarding classes from 8 to 16 and the number of supported loss priorities from 3 to 4. This enhancement enables you to classify all available 64 Differentiated Services code point (DSCP) values.

    You can also configure the loss priority as medium-low at the following hierarchy levels:

    • [edit class-of-service classifiers cls-type classifier-name forwarding-class class-name loss-priority]
    • [edit class-of-service rewrite-rules rw-type rewrite-name forwarding-class class-name loss-priority]
